The idea of wage slavery is often regarded with suspicion even among critics of capitalism. Sceptics note the dubious racial politics associated with its use, while recording many differences between the condition of waged workers and chattel slaves. However, these objections are more plausible on some conceptions of wage slavery than others. I look to the history of political thought to recover and reformulate a more defensible account, drawing on a neo-Roman understanding of slavery as subjection to another’s will (rather (...) than as ownership or social death). I demonstrate not only that a neo-Roman vocabulary was taken up by abolitionists, but recount how radical republicans used it to criticise the wage relation and call for the socialisation of property. This neo-Roman approach is shown to represent a break with more paternalistic appeals to wage slavery made by Tory radicals and Southern apologists for chattel slavery. However, in order to avoid cheapening the accusation of wage slavery, I argue that it only obtains when a worker’s ability to meet their most vital material needs is dependent on the will of employers. Thus, wage slavery becomes an extreme form of economic unfreedom, which does not encompass every case of worker domination. (shrink)
